Qnegof `tlieobjec-ts of .the invention is to provide ai istr.uct-ure` which can be` erected in` about onetenththe time it takes to build a wooden scaffold, and (one which` is .more substantial, safer, and more Adurable than, a Wooden scaffold,` and `in Whl hno partici' timbers ofthe scaffold is Wasted when assessors is dismantled.

Referring 'to `the dravvings, 6` designates baseV I plates having upstanding pegs` 1 rigidly connected thereto. c Four of these baseelements'are used-Y at. the` corners 0f a unit of the scaffold, and the pegs are` adaptedto extend into sockets 8 fat the lower` .ends of thejoint` elements 9. `Each of. these lelements.has an upstanding socket I0 `co;

axial with` the` axis` of the socket 18V, and four horizontallydisposed sockets II radiating` from saidl axis andpositioned at .90? relative to, one` another,-` `Thesockets are `jointed by Webs"` I2, each o f Which-,has an aperture I3` for a purposehereinaiter described. c

orfpipes I4 have their ends, extending intosockets lll of` four of the` units 9 so as to make la complete `rectangle. Four vertical rigid posts .or pipes lghavetheirilower ends supported bythe sockets I0, and they are capped by Joint elements 9a identicatwithfthe;elements" 9.2 Other horizontal rods or pipes I6 have their ends connected to horizontal sockets ofthe elements 9a` so as to form a rectangular frame atthe top of the unit,

structure around a corner, `or the like.

- securedto the barby a pivot pin `3|).` It will be obvious that a pin passed through hole 28 andI any one of the holesizv'l `will act to secure the i `hinge socket at various angles tothe bar 25 so that thesocketfl may beplaced in` position to receivehorizontal bars I4, I6 in extending the From the foregoing, vit is believedthat the structure, use and advantages ofthe improved c `scaffold. may be readily understood by .those skilled in theart,` and it Will beA apparent that `the various elements aredetachably connected; to one another so that one or more units may be c erected by properly assembling the elements. i It Y is alsozmanifest that a unit can be extendedfrom either side of theunit illustrates; by" the use of other horizontal bars, and the unit may fbe increased inheight by adding vertical posts 44to the top sockets ofthe elements 9a.y c

While I have disclosed What now consider to be a preferred embodiment of the invention, it is obvious that changes may be made in the details disclosed Without departing from the spirit 1 of the invention, asLeXpressed in the claims. What I claim `and desire; to secure by Letters Patent is:
